Former New Mexico Gov. Gary Johnson won the Libertarian Party's presidential nomination Sunday. He secured the win on the second ballot of the Orlando, Florida, convention with 55.8 percent of the vote.

Johnson, also the Libertarian Party's pick in 2012, has been polling in the double digits against both Hillary Clinton and Donald Trump. To qualify for televised debates, he'll need to hit 15 percent. Julie Kliegman

Democratic presidential hopeful Bernie Sanders picked up 49 of 67 delegates divided up by Washington, according to district-level data released Saturday to The Associated Press. The Vermont senator adds that to the 25 of 34 delegates he picked up with his March caucus win in the state.

Even with that haul, Sanders trails far behind frontrunner Hillary Clinton, who has about 94 percent of the delegates needed to win the nomination. Sanders has vowed to stay in the race through the Democratic National Convention in July. Julie Kliegman

Rep. David Jolly (R-Fla.) is stumped. In an interview with AM970 The Answer's Effective Radio, Jolly said he doesn't know if he'd back Donald Trump in a November matchup.

"I have strong reservations about some of Donald Trump's solutions to some of the security issues we face as a country. Those are real reservations," he said. "Now, I will tell you I also have strong disagreements with Secretary Clinton over her view of foreign policy. So, I think like a lot of Americans, we are gonna have to begin to spend the summer studying the candidates and decide who's best for the future of the country."

UPDATE 3:20 p.m.: Jolly's campaign told BuzzFeed News that he would not vote for Clinton. "David Jolly is on the record saying he will never support Hillary Clinton in November," campaign manager Max Goodman said. "His position has not changed." This post has been updated throughout to reflect that stance.

Sen. Ted Cruz (R-Texas) picked up about 80 delegates of more than 170 on the table at local and state conventions Saturday, Politico reports.

He snagged a majority of delegates in Arizona and Virginia, two states that strongly backed Donald Trump in primaries. Cruz also made gains in Missouri. Trump fared well in Massachusetts, Alaska, and Arkansas.

Most delegates are obligated to support the winner of their state's nominating contest on the Republican National Convention's first ballot, but can switch allegiances in future rounds of voting. Cruz's strategy banks on Trump not being able to grab the minimum of 1,237 delegates needed to secure the party's nomination outright. Julie Kliegman

Sen. Ted Cruz (R-Texas) is considering former opponent Carly Fiorina as his pick for vice president, the former Hewlett-Packard CEO's spokeswoman told The Weekly Standard on Monday.

"We've already announced publicly that we're vetting prospecting VP nominees, but no selection has been made yet," Cruz's spokeswoman said after word got out. "When that decision has been made, we will share it."

Conservative billionaire political donor Charles Koch won't be in attendance at July's Republican National Convention, he told ABC News in an interview published Monday. Neither will his fundraising network, Freedom Partners, which he partially funds alongside his brother, David.

"Why go?" Koch said. "We're not interested in politics. We're interested in moving us towards a culture and policies that will enable people to improve their lives."

Koch also criticized the conservative support for House Speaker Paul Ryan (R-Wis.) as president, saying he shouldn't be considered a contested convention's "white knight." His negative feedback for the GOP follows his Sunday assertion on ABC that "it's possible" Hillary Clinton is the strongest presidential candidate. Julie Kliegman
